Abstract: PURPOSE:To make it possible to vary the state of opening of a screen, freely and simply, by a method each member for going up and down is fitted with a pulley, its pulley is mounted on the output shaft of a self-lock type motor, and its motor is suspended on a bracket. CONSTITUTION:An ultrasonic type motor (16), is suspended on a bracket (12), a pulley (14) is mounted on the output shaft (18) of the motor (16), and the pulley is fitted with the top end of a cord (15). An encorder (19) detecting the number of revolution is provided with the ultrasonic type motor (16). On the other hand, a driving control circuit is controlled by micro computer. The micro computer contains circuits as follows: the circuit for detecting the number of revolution, where it counts the number of revolution by receiving a signal out of the encoder of each ultrasonic type motor; the circuit for setting the number of revolution of each motor; and the checking circuit, where it outputs a signal to each drive control circuit by comparing the number of revolution of each motor with the number of revolution setting. When a switch is turned on, each ultrasonic motor is revolved with only the same number of revolution as setted on the motor, in the direction for winding the pulley or in reverse. On the other hand, when a signal is outputted from checking circuit to driving control circuit, the revolution of the motor is stopped.

Title: Stereo-lithographically formed mold
Inventor: WADA KIYOSHI
IPC: B29C67/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce the adhesion due to the biting developed by the shrinkage of a molding resin and, at the same time, prevent the crack and separation of a surface layer from developing due to the heat of the molding resin by a method wherein a plurality of layers are formed on the surface of a formed mold. SOLUTION: A stereo-lithographically formed mold 12 has an easily broken projecting part 12. On the surface of the stereo-lithographically formed mold 12, three film layers 13a, 13b and 13s are formed. The stereo-lithographically formed mold 12 is made of urethane acrylate added with inorganic substance. The first film layer 13a is made of zinc. The second film layer 13b is made of aluminum. The third film layer or surface layer 13s is made of nickel. The nickel employed in the surface layer is excellent in the releasability of the molding resin and has a small surface roughness. For example, the surface roughness of the surface layer 13s is set to be 10μm or less.  Due to the small affinity between the molding resin and the film material of the surface layer 13s and the small surface roughness of the surface layer, through a resin molded article contacts with the surface layer 13s of the stereo-lithographically formed mold 12, the adhesion of the molding resin to the mold is small, resulting in preventing the breakage of the mold at the ejection of the article from occurring.

IPC: C07H3/10
Filed: 1988-03-01
Abstract: PURPOSE:To obtain saccharides which are used as a diet food, because of its difficult digestiveness, by irradiating polysaccharides with CO2 laser to melt the saccharide and cause fission of the bonds between monosaccharides without increase of hydroxyl groups. CONSTITUTION:So-called polysaccharides such as starch or cellulose are compressed and placed on the bed 13 and irradiated with CO2 laser, as the defocus value is determined and the bed is rotated, so that the polysaccharides are melted to cause fission of the bonds between monosaccharide units. Thus, the polysaccharides are decomposed without increase in hydroxyl groups to give a low-molecular compound soluble in water.

Title: Single phase auto transformer
Inventor: OKAMURA KATSUYA
IPC: H01F29/02
Filed: 1982-03-29
Abstract: PURPOSE:To provide a small size single phase auto-transformer in which the tertiary voltage does not change by the position of the tap winding and has a small zero phase impedance and a small installation area by providing a first and second iron core legs on the same iron core. CONSTITUTION:As a zero phase circuit there are two circuits, a tertiary winding 3 and a stabilizing winding 8. The zero phase circuit by tertiary winding 8 has no change from the conventional circuits and has a large zero phase impedance. On the other hand, since the stabilizing winding 8 is provided on the main leg 91 of single phase three-leg iron core, the induced voltage per one turn is two times the induced voltage when it is provided on the side leg 92. The zero phase impedance by the stabilizing winding 8 is smaller compared with tertiary winding 3. This can be interpreted that, since the zero phase impedance as seen from high voltage terminal U or medium voltage terminal (u) is the parallel circuit of the stabilizing winding 8 with small impedance and a tertiary winding 3 with large impedance, it is almost determined by the stabilizing winding 8 with small impedance. Accordingly since the stabilizing circuit is not connected to load, its capacity can be small, and the winding on the main leg 91 of a single phase three-leg iron core gives little effect to the size of transformer.

Title: Manufacture of barium ferrite superfine particle for magnetic recording
Inventor: NAGANAMI TAKESHI
IPC: G11B5/706
Filed: 1986-03-06
Abstract: PURPOSE:To obtain flake brium ferrite efficiently, particle size of which extends over 0.05mum or less and which has a large specific surface area, by adding and agitating a specific quantity of excess alkali hydroxide salt to an alkali aqueous solution, charging slurry formed to an autoclave and treating the slurry at a specific temperature. CONSTITUTION:Excess alkali hydroxide salt at 7-11mol/l is added to an alkali aqueous solution, into which iron and barium and the like are dissolved, and agitated. Slurry containing precipitates formed is charged into an autoclave, and treated while being stirred at 150-190 deg.C. Consequently, superfine particles having a large surface area can be manufactured. Accordingly, the temperature of hydrothermal synthesis is kept within a range of 150-190 deg.C, thus remarkably fining ferrite particles formed, then acquiring products in 0.05mum or less. Said iron (FeIII) and barium (BaII) each take the shapes of known sulfate, nitrate, chloride, hydroxide, etc., and sodium hydroxide, potassium hydroxide, etc., are preferable as alkali hydroxide.

Title: Carbon dioxide concentration detection apparatus
Inventor: ITO YUICHIRO
IPC: G01N27/406
Filed: 1992-03-06
Abstract: PURPOSE:To enhance the accuracy of a carbon dioxide concentration detection apparatus by improving the latching treatment of a reference value when the carbon dioxide concentration detection apparatus is calibrated. CONSTITUTION:The maximum value within a prescribed time (a) of signals from a carbon dioxide sensor 101 is stored in a maximum-output-value storage means (a) 102; the maximum value is stored in a maximum-output-value storage means (b) 1 only for a prescribed time (b). A group of maximum values which have been stored in the maximum-output-value storage means (b) 1 are weighted respectively by their dispersion; they are weighted by the difference from a reference value; the reference value is computed in a reference-value computation means 2. Thereby, the accuracy of the reference value is enhanced. In addition, when the maximum value is latched into the maximum-output-value storage means (a) 102, the stability of outputs is detected by using a sensor-output-stability detection means 6 so that the latching accuracy of the maximum value is enhanced. In addition, the state of a measuring atmosphere is known from the outputs of the sensor by using a sensor-output-value- dispersion monitoring means 7. Thereby, the proper maximum value is latched. In addition, the maximum value is monitored by means of dispersion degree and the reference value by using a maximum-value storage and monitoring means 8. Thereby, the reference value can be renewed stably.
